Quite an adventurous career: https://www.nytimes.com/2022/07/15/arts/music/david-dalton-dies.html
My prime recommendation is James Dean, The Mutant King, which explains Dean’s persona breakthroughs with brilliance. Makes his early death seem even more tragic. Revived interest in him altogether.
My more unconventional pick is Mindfuckers, pretty obscure these days, but an unmatched examination of how certain sociopaths were able to use counterculture guru-worship for evil.

I’ve been prodded to note a peculiar, invertoid connection between my two recommendations. The book behind Dean’s most famous work, “Rebel Without a Cause,” is in fact a study of sociopathology, whereas Dean gave his rebel a very vivid target — square, youth-hating society. And then, “Mindfuckers” shows how true sociopaths have turned the same aura of rebellion into an evil cult that can become murderous.
